Growing Verbena: A Complete Profile
By Growing Home Greens Team · July 18, 2026
Verbena is a low, spreading groundcover flower that does most of its work at ground level, filling gaps between taller plants and covering bare soil with color through the hot months.
What to expect
Direct sow about a week after your last frost — exact seed depth isn’t well documented across sources, but the general guidance is to cover lightly rather than bury it. An Arizona gardening source specifically recommends scattering seed straight into the landscape near drip emitters rather than starting it in pots, which fits verbena’s low-fuss, direct-sow nature generally. At half a plant per square foot, give it room to spread; it’s often grouped with desert marigold in native and desert-style plantings, and it fills in as a sprawling mat rather than staying in a tidy clump.
Common problems
Sparse, leggy growth usually traces back to too little sun — verbena wants full sun to perform as the dense, spreading mat it’s known for. If germination is patchy, it’s often a seed-depth issue in either direction: buried too deep and it won’t emerge, left fully exposed and it dries out before it can root.
Where this fits in your garden
Verbena isn’t linked to specific companions or antagonists in our data — see the full companion guide for verbena for how it’s tracked. Its spreading, low-growing habit makes it a natural fit for edges and gaps in the Garden Designer rather than a dedicated square of its own.

Varieties worth considering
- Homestead Purple — Clemson Cooperative Extension's Home & Garden Information Center calls it one of the most popular trailing verbenas, citing excellent heat tolerance and profuse blooming from early spring until fall frost — a good default if you don't have a strong color preference. (source)
